Abstract in brief
Analysis of Tyrannosaurus rex tissue shows preserved collagen I, the main organic bone component, in low concentrations.
Multiple tests, including mass spectrometry, confirmed the presence of this protein independently.
This discovery could support theories about dinosaur evolution, molecular change over time, and the chemical stability of ancient proteins.

Pour le pool de gènes, je ne sais pas d'ou il tire ça, puisque les fossiles n'ont pas de gènes.
On pourrait penser qu'il fait référence aux séquences d'acides am, mais elles sont proches des oiseaux aussi. DOI: 10.1126/science.1138709
@___loth___ @darwintojesus You asked how we know the protein is authentic and how it's survived. Schweitzer et al. used rigorous demineralization, microscopy, immuno-assays and mass spectrometry to detect collagen I fragments from T. rex, matching bird collagen.
